Zinc zirconate (ZnZrO3) nanocomposites bimetallic designed by green synthesis via Moringa Olefeira extract for high-performance electrochemical applications

In this work, we report a simple and eco-friendly method of synthesizing ZnZrO3 nanocomposites by green approach method using Moringa Oleifera natural plant extract that acted as both capping and reducing agent via their photochemical. The proposed mechanism towards the formation of ZnZrO3 nanocomposites in view of understanding the interaction of Zn (II) and Zr (IV) ions through biological compounds of Moringa Oleifera extract was designed from FTIR analysis. The electrochemical analysis clearly revealed redox peaks at around peak potentials of 0.075 (peak III) and - 0.563 V (peak IV) during the cathodic cycle, due to the reduction and around - 0.252 (peak I) and 0.207 (Peak II), corresponding to the oxidation of ZnZrO3 nanocomposites. The excellent electrochemical performances suggest that ZnZrO3 nanocomposites are highly suitable for electrochemical applications due to good voltammetric response, high electro-activity and good electrochemical kinetics.
